ERNEST G. JONES AND THOMAS T. PATCHEL, OF CAPE MAY, NEW JERSEY.

ROTARY Application led April 11,

7b all whom t may concern Be it knownt-hat we, ERNEST G. JONES and Tnoims T. LAfronnn, citizens of the United States, residing at Cape May, in the county of Cape May and State of New Jersey, have invented certain new and useful Improvements in Rotary Engines, of which the following is a specification.

The present invention relates to certain new and useful improvements in rotary engines, and has forl its object to provide an engine of this character which embodies novel features of construct-ion whereby the expansive power of the steam or other elastic fluid medium may be utilized to the best possible advantage in driving two concentric rotors mounted to revolve in opposite directions.

Further objects of the invention are to provide a rotary engine which is comparatively simple and inexpensive in its construction, which is economical in the use of steam or other elastic fluid medium, which is capable of developing great speed and power, and which can be readily assembled and taken apart as may be found necessary.

1With these and other objects in view, the

linvention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description prolceeds, the novel features thereof being Fig. l, looking in the direction of the arrow.

Corresponding and like parts are referred to in the following description and indicatedin all the views of the drawing by the same reference characters.

Specification of Letters Patent.

Specifically describing the present embodi- ENGINE.

1913. Serial No. 760,429.

ment of the invention, the numeral 1 designates the exterior casing or shell which may be formed in any suitable manner, although it is preferably constructed in two complemental sections which can be assembled by applying the same to the rotors from opposite sides thereof. This outer casing or shell l is substantially cylindrical in shape and may be held rigidly in posit-ion in any suitable manner as by means of the supporting brackets 2.

Opposite sides of the casing l are formed with the alined and axially disposed bearings 3 which serve to receive the inner ends of the hollow shafts 4 and 5. The hollow shaft 4 carries a rotor 6 which has a hollow formation vand is substantially cylindrical in shape. The end portion of the shaft 4 extends axially through the rotor 6 so as to have a positive engagement with both side walls thereof, and is provided with a series of lateral openings 7 Which communicate with the interior of the rotor. The periphery of the rotor 6 is provided with a series of nozzles 8 which are arranged at equidistant intervals and are inclined in the same direction at an angle of substantially 45 to the radius. The periphery of the rotor 6 is also provided with the buckets 9 which are arranged between the nozzles 8 and are also inclined in the same direction at an angle of substantially 45 to the radius. The various nozzles 8 all communicate with the interior of the rotor 6 so as to receive a continuous supply of steam or other elastic liuid medium therefrom, the said steam or elastic fluid medium issuing from the nozzles in a series of jets.

A second rotor 10 is carried by the inner end of the hollow shaft 5, the said rotor l() comprising a comparatively shallow body portion l0a which is arranged at one side of the rotor 6, and a hollow rim portion 10b which projects laterally from one side of the body portion l()al and overhangs the inner rotor 6. The shaft 5 projects axially through the rotor 10 so as to have a positive engagement with both side walls thereof and is provided with the lateral openings ll which communicate with the interior of the rotor.

Patented Nov. 18,1913. f

The annular' rim portion 10b of the rotor 10 is provided upon the inner periphery thereof with an annular series of nozzles 12 and with the buckets 13 which are arranged between the nozzles, both the nozzles and the buckets being inclined in the same direction at a angle of substzintially 45 tothe radius. Theouter periphery of the annular rim 1t)b of the rotor'10 is also provided with an annular series of nozzles 14 and with the intermediate series of buckets 15. These nozzles 14 and buckets 15 are inclined in an opposite direction to that of the interior nozzles 12, so that the reaction resulting from the jets issuing from the inner nozzles 12 and outer nozzles 14 will tend to revolve the rotor 10 in the same direction.

A hollow annular steam ring or chest 16 surrounds the outer rotor 10 and is rigidly supported within the casing 1 in any suitable manner as by means of the brackets 17. The top of the steam ring 16 communicates with a steam supply pipe 18, while the inner periphery of the steam ring 1G is provided with a series of nozzles 19 which are inclined in the same direction and at an angle of about 45 to the radius, the jets from the nozzles 19 being directly opposed to the jets from the outer nozzles 14 of the rotor 10. The sides of the steam ring or chest 16 are slightlyl spaced from the sides of the. casing 1 to admit of the expanded steam escaping around the sides thereof into the outer periphery of the casing 1, an exhaust pipe 2O being providedfat the bottom of the casing.

In order to reinforce the over-hanging annularrim portion 10b of the rotor 10 against the centrifugal force which would be incident to high speeds, the outer side of the said overhanging annular rim portion 10b of the rotor 10 is connected by radial arms 21 t@ a ring 22 which fits loosely between the casing and the inner rotor 6, forming in effect a spider which has av truss action and will effectively lreinforce the ovcrhangin; peripheral portion of the outer rotor 10 against the strong centrifugal forces which 'are incident to high speeds.

The hollow shafts 11. and 5 project from opposite sides of the casing 1 and r hewn as journaled in bearings 23V at the upper ends of standards 24. These hollow shafts 4 and 5 serve to supply the steam or other elastic fluid medium to the hollow rotors 6 and 10, each of the shafts having a suitable swivel action, as indicated at. 25 with a steam supply pipe 26. lt will also be observed that each of the hollow shafts 4- and 5 is provided with a suitable pulley 27 by megas which power may be taken from *satanic for driving any desired machinery performing any useful work.

The nozzles 8 of the rotor 6 are arranged to just clear the inner nozzles 12 of the outer the rotor 10 are directly and oppositely dis- Vvarious buckets also serve to cooperate with rotor 10, while the outer nozzles M'of the rotor 1() are arranged to just clear the nozzles 19 of the steam ring 16. The steam from the hollow shafts 4 and 5 enters the interior of the respective rotors 6 and 10 and issues from the various nozzles of the rotors in a series of jets, the jets issuing from thev nozzles 8 o f the rotors 6 are directly opposed to the jets issuing from the inner nozzles 12I` of the rotor 10, so thatI the two jets react upon each other and tend to drive the two rotors 6 and 10 continuously in'opposite directions. In a similar manner the jets of steam issuing from the outer nozzles 14 of posed to the jets issuing from the nozzles 19 of the annular steam ring 18 so that the two sets of jets react upon each other and assist in the driving of the outer rotor 10. The

thejjets of steam to drive the rotors. After the', expansive force of the steam has been utilized it escapes around the sides of the rotors and hollow steamring 16 to the outer periphery of the casing 1, and from this casing through the main exhaust pipe 20. It will thus be obvious that the two rotors 6 and 10 will be driven in opposite direc. tions at` a high rate of speed, and the power generated by the two rotors may be utilized 9 for performing useful work through the medium of the drive pulleys 27.
